Nws yog qhov zoo tshaj plaws uas neutron tsis yog nrhiav pom mus txog rau xyoo 1932 thaum James Chadwick siv cov ntaub ntawv tawg paj los xam cov huab hwm coj ntawm qhov nruab nrab no.

Ib yam li ntawd ib tug yuav nug, Rutherford nrhiav tau lub neutron li cas?

Nws yog James Chadwick, tus kws kho mob Askiv Askiv thiab tus neeg ua haujlwm ntawm Rutherford , who nrhiav pom thib peb subatomic particle, lub neutron . Chadwick bombarded beryllium ntawv ci nrog alpha hais thiab pom ib tug nruab nrab hluav taws xob tawm los. Qhov hluav taws xob nruab nrab no tuaj yeem cuam tshuam cov protons tawm ntawm nuclei ntawm lwm yam khoom.

Kev soj ntsuam dab tsi ua rau kev tshawb pom ntawm neutrons? Rutherford tau tshaj tawm tias muaj qee qhov nruab nrab qhov nruab nrab uas muaj huab hwm coj zoo ib yam li proton tab sis tsis muaj pov thawj ncaj qha. Muaj ntau txoj kev xav thiab kev sim kev soj ntsuam thaum kawg coj tus nrhiav pom ntawm neutron . Brainly Answering Legend Contest yog nquag.

Tsuas yog li ntawd, leej twg nrhiav tau lub neutron thiab nrog dab tsi sim?

Rutherford thiab Chadwick tam sim ntawd pib qhov kev sim ntawm Cavendish Laboratory hauv Cambridge los tshawb nrhiav cov neutron. Cov kev sim tau txuas ntxiv mus thoob plaws xyoo 1920 yam tsis muaj kev vam meej. Rutherford qhov kev xav tsis tau lees paub.

Rutherford puas paub txog neutrons?

Xyoo 1919 Rutherford tau tshawb pom cov proton, ib qho kev them nqi zoo nyob rau hauv lub atom lub nucleus. Tab sis lawv thiab lwm cov kws tshawb fawb tau pom tias cov proton ua tsis zoo li tsuas yog ib feem ntawm lub nucleus. Nws hu ua a neutron , thiab xav tias nws yog ib tug khub proton thiab electron.
